To aZZ whom t may concern.'

Be it known that I, Ciins'rnnihl LYMA, a citizen of the United States, residing at the city, county, and State of New York, have invented certain new and usefulv Improvements in Holder and Severing Devices for Paper-Rolls; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Myinvention relates to fixtures for holding rolls of paper, and for severing therefrom strips which have been drawn ofi1 to the appropriate length. It has been particularly developed for use in connection with the rolls of paper toweling which have in recent years come into wide use. I`he object of the invention is to provide a simple and effective device of this character from which the paper may be drawn and severed by the user, with one hand, so as to avoid the inconvenience attendant upon the use of both hands, particularly when the hands are wet. A

The invention consists broadly inproviding a rotatable paper-roll support of such character that the paper may be drawn from the roll freely at a convenient angle until the desired quantity has been Unrolled, -but upon slightly changing the angle 'of withdrawal of the paper, the roll-will be positively locked against rotation, thereby permitting the paper to be torn off. T his object may be effected, for example, by causing the change in the angle of withdrawal ofthe paper to throw or drop alocking pawl into engagement with a ratchet wheel on therotatable roll support. For the purpose ofaiding in the severing of 'the paper ,after` the roll is locked, I may convenientlyl provide a serrated or straight edge constituting a cutter against which the paper is drawn when its angleof withdrawal is changed; and'in the preferred embodiment of the invention hereinafter illustrated and described the cutter is employed as the instrument through which the locking pawl is actuated. In this preferred arrangement, the cutter, uponbe# ing engaged by the paper, acts to stop the i rotationlof the roll, thereby permittingthe tearingofff of the paper along the straight @deemed preventing,overlunaing-g The rrangement is. preferablyH such'.A that the Patented Nov. 13, 1917. s

paper tube which constitutes the. core of the roll is held against rotation on the shaftof the roll support, as willbe understood from the following description, and I haveifurn thermore described and claimed certain par; ticular features of .novelty which, in" the specific form disclosed, are not essential to the invention, but which I prefer` to employ.

In the drawings, Figure l is an end elevaition of the Xture with the roll of paper in position and showing in dotted Ylines the position yof the cutter and paper when the vstrip is being torn off;

Fig. 2 is afrontelevation of the` same parts, showing thefpaper and the cutter'in the position. which they have assumed Yby gravity, and in this ligure a portion ofthe rollis'broken away to show more clearly the controlling pawl and ratchet anda convenient means for holding the roll against rotation on the shaft;

' Fig. 3 is a fragmentary section of the.Y end of the shaft showing in greater detail the mechanism for holding the roll againstrotation thereon; andv `Y p Y Fig. 4 is a cross-section on the line 4-4 `of Fig. p `Similar letters of reference indicate like 'parts in the several figures.

A represents a support, such as a wall, or the like, to which the base-plate BY of the fixture is attached, andthe ybase-plate has two outwardly extending bracket arms B which are providedwith bearingsA C, C for the roll supporting shaft I). It will be understood that one of the bearings, as C', will be Open at the top so that the end of the shaft maybe dropped intoit after the other end: has been inserted in the bearing C. The roll of 'paper shown is ofthe kind now so generally used for towels and vis wound on a paperfor pasteboard vtube E'Yof a length equal tothe widthl of thepaperaend ido slightly less than the length of the shaft D, upon which the tube is slipped and which constitutes the axle :tor the paper roll. As shown, the shaft D is of metal tubing and is provided at one end with projecting shoulders or wedges G adapted to enter corresponding slits or notches in the tube E, as shown in Figs. 2, 3V and il, for the purpose of holding the paper roll against rotation on the shaft, andY thereby causing the shaft to rotate when the paperV is drawn from the roll.v In the ends of the shaft D are tightly tted plugs AH` carrying the hubs or trunnions upon which the roll is mounted in the bearings (1,'0. The plug in that end of the roll which abuts ther bearing C has a simple cylindrical extension constituting the hub which lies inV that bearing, but the plug in that end ot' the roll which abuts the bearing C is of the modified form shown in Fig. 3 of which the portion H ot' greater diameter carries a ratchet wheel J while the reduced portion I is of a size to fit within the bearing C.

The cutter consists orp the depending arms K, K pivoted to the bracket arms B, as shown, and carrying at their lower end the serrated edge L. Although the edge L is shown serrated, it will be understood that a straight edge may be employed if preferred. The'arm K carries a pawl or dog L adapted to engage Vthe teeth of the ratchet wheel J when the arms are moved outwardly through a small angle, and a stop M ispreferably provided against which the depending cutter .arm K rests when hanging in the position shown in full lines in F ig. l.

The operation of the device is as follows:

The shaft D is inserted in the tube E until the wedges G engage the slits or notches in the tube E, and thereby hold the paper roll against rotation on the shaft. The hub I is then inserted in the bearing C and the projecting hub at the other end of the roll is laid in the bearing C. I'Vhen itis desired to tear off a strip of paper, the user with one hand grasps the paper` and draws it downwardly until the desired length has been unrolled and then draws it outwardly against the cutter until the part K engages the teeth of the ratchet wheel J, thereby locking the roll against the further rotation. whereupon the paper is severed by tearing it along the serrated edge as will be readily understood. When this has been accomplished, the cutter returns by gravity to the posit-ion shown in Fig. l in full lines, in which the paper roll is again freed, and because of the angular relation of the paper to the cutter, the free end of the paper will hang below the cutting edge. as illustrated in Fig. 2, and may conveniently be grasped for tearing oil another strip. p

It will be observed that in the fixture described simple means are provided for locking the paper roll on the shaft of the holding fixture, and that the paper may be drawn out the desired length and then severed from the roll by a simple and natural movement which may be accomplished by one hand, and that the cutting action positively locks the roll to assist the severing and to prevent overrunning. In addition to the convenience ofy operation, the fixture has the advantage Vthat unperforated rolls kof paper may be employed, thus cheapening the manufacture and at the same time enabling each user to decide for himself the length of paper which he will use.

Although I have thus described in det-ail 80 is positively locked to permit the tearing ofi1 90 of the desired length of the paper strip;

and the claims appended hereto should have a correspondingly broad interpretation.

lVhat I claim is:

l. A holder and severing device for paper 95 rolls comprising a rotatable roll-support from which the papermay be freely drawn at a convenient angle, a locking element carried by said roll-support,Y and a second locking element actuated by the paper upon thereof to engage the first locking element and positively lock the roll-support against rotation.

2. A holderand severing-device for paper 10b rolls, comprising a rotatable roll support carrying a ratchet wheel, a locking pawl normally withheld from engagement with the ratchet wheel, and means actuated by the paper at a given angle of withdrawal to bring the pawl into engagement with the ratchet wheel and positively lock the roll support against rotation.

3. A holder and severing device for paper rolls, comprising a rotatable roll support from which the paper may be withdrawn at a convenient angle, said support being provided with means or holding a paper roll against rotation with respect thereto, and a locking device actuated by the paper upon slightly changing the angle of withdrawal thereof to positively lock the roll support against rotation.

4. A holder and severing device for paper rolls comprising a rotatable support-for the roll, a locking element carried by said support, a cutter, and a second locking element actuated by the contactof the paper with 'slightly changing the angle of withdrawal the cutter to engage the first locking element the rotation of the roll during the severing and prevent the turning of the rotatable supoperation. 10 port during the severing operation.
